Thoracic actinomycosis with involvement of the vertebral column and chest wall is rare in children and may resemble malignant tumors. A 12-year-old girl was admitted to our clinic having B-symptoms, cachexia, and painful scoliosis (Karnofsky index 20%). Imaging showed a large thoracic left-sided paravertebral tumor with infiltration of the vertebrae, destruction of the chest wall and multiple intrapulmonary nodules. Initially, Ewing sarcoma was suspected and chemotherapy started without previous biopsies. Definite diagnosis of actinomycosis was established later upon histopathologic examination and successfully treated by β-lactam antibiotics...

Periapical actinomycosis caused by a gram-positive anaerobic pathogen characterizes a typical extra-radicular infection. This study determined the frequency and correlated the content of bacteria colonies with the of periapical actinomycosis size. The study comprised a total of 218 periapical lesions (PL) (cysts, granulomas or abscess). The specimens embedded in paraffin were sliced into 4-µm sections and stained with hematoxylin-eosin, Gram, Periodic Acid-Schiff (PAS) and Grocott's stain. The presence of bacterial colonies composed of filamentous structures labeled with the histochemical stains were described as Actinomyces, and for each case, the bacterial colonies were counted and measured...

BACKGROUND: Actinomycosis is a chronic and extensive granulomatous, bacterial infection. Revelation by oral ulceration is rare. PATIENTS AND METHODS: A 76-year-old patient with diabetes was treated with dabrafenib for stage IV melanoma. A follow-up visit revealed two ulcerated, infiltrated and hyperalgesic lesions of the palate and gingiva. There were no associated signs. The laboratory findings were normal. The possibility of squamous cell carcinoma occurring with BRAF inhibitors was discussed, despite the rarity of such cases in the literature...

A 60-year-old man presented with odynophagia after bronchial artery infusion chemotherapy for pulmonary metastasis of hepatocellular carcinoma. Esophagogastroduodenoscopy (EGD) revealed an esophageal ulcer in the middle thoracic esophagus. An esophageal biopsy demonstrated no malignancy. However, the symptoms had not improved after a month. EGD was performed again and showed a white cord lump at the bottom of the same esophageal ulcer identified before, showing no improving tendency. A repeated biopsy of the lump revealed actinomycosis, and the symptoms were improved by the oral administration of ampicillin...

Actinomycosis is a form of painful abscess in the gastrointestinal tract or in deep tissue caused by actinomyces species. They are one of the commensal bacteria in the oral cavity and gastrointestinal tract of humans but can opportunistically cause infection in immunosuppressive hosts through invasion of breached mucosa or necrotic tissue while mimicking malignancy, gastrointestinal tuberculosis, and inflammatory bowel disease. Actinomyces israelii is, by far, the major and most common human pathogen throughout literatures...

BACKGROUND: Granulomatous disease in the thyroid gland has been linked to viral, bacterial and autoimmune etiologies. The most common granulomatous disease of the thyroid is subacute granulomatous thyroiditis, which is presumed to have a viral or post-viral inflammatory cause. Bacterial etiologies include tuberculosis, actinomycosis, and nocardiosis, but are extremely rare. Disseminated actinomycosis and nocardiosis more commonly affect organ-transplant patients with the highest susceptibility within the first year after transplant surgery...

Aspergillosis is a common systemic mycosis which affects immunocompromised and immunocompetent hosts. Aspergillus spp. is wide spread in the environment in most countries, which renders an invasive form of disease. The presence conidial heads are pathognomic to aspergillosis in diagnosis. Actinomycosis is a subacute-to-chronic infection that causes sinus fistula, tract or abscess due to the invasion surrounding the soft tissue. Cervicofacial infection accounts for 50%-60% of all actinomycosis cases. The mandible and nasopharynx are the sites of predilection, but maxillary infection is rare...

Background: Actinomycosis is a condition in which Actinomyces, a normal component of the oral and gastrointenstial flora, becomes pathogenic in the setting of damaged tissue, leading to widespread tissue destruction across fascial planes. Prior literature describing this condition is rare, particularly cases involving the retroperitoneum. In this study, we report a case of retroperitoneal actinomycosis caused by an infected, obstructing ureteral stone. Case Presentation: A 48-year-old woman with a history of substance abuse, malnutrition, and gastric bypass presented to the emergency room with a 3-week history of abdominal pain and fevers...

Pulmonary actinomycosis is a rare yet important and challenging diagnosis to make. It is commonly confused with other lung diseases, such as tuberculosis and bronchogenic carcinoma, leading to delay diagnosis or misdiagnosis. A 49-year-old man presented with a chronic cough, hemoptysis, and pleuritic chest pain. His initial imaging studies including computed tomography (CT) was suggestive of bronchogenic carcinoma. A subsequent CTguided biopsy was consistent with pulmonary actinomycosis and excluded the possibility of bronchogenic carcinoma...

Actinomyces meyeri is a rare pathogen and an infrequent cause of human actinomycosis. Less than ten cases were reported in the English-literature to date concerning A. meyeri empyema. We herein report a case to promote the awareness and adequate management of the disease. A 44-year-old immunocompetent male with known pulmonary disease was diagnosed with an A. meyeri empyema. He underwent chest tube drainage and a short-term treatment with clindamycin for 4 months. This is the first report of a patient with structural pulmonary disease with an A...

Mycetoma is a chronic infection, characterised by severe disability and discomfort to patients. This condition is common throughout tropical regions of the world. The Indian subcontinent and north-east Africa, especially Sudan, bear the majority of the disease burden. Due to the limited resources and isolation of these areas, the condition is usually misdiagnosed or incorrectly managed. The World Health Organisation listed the condition as a "neglected disease" in 2013. The creation of the Mycetoma Research Centre (MRC) by the University of Khartoum in 1991 has greatly contributed to the current understanding of this disabling condition...

Actinomycosis is an infrequent chronic infection regarded as the most misdiagnosed disease by experienced clinicians. The Office of Rare Diseases at the National Institute of Health has also listed this disease as a "rare disease." This article presents a case report of actinomycosis of the alveolus with unusual clinical features but a successful resolution. It also states the importance of biopsy of deceptive inflammatory lesions that do not respond or recur after conventional treatment modalities.

We report a rare case of lung abscess due to Eubacterium brachy. In this case, an analysis of the aspirate from frank pus revealed Gram-positive coccobacilli. We initially strongly suspected lung abscess associated with actinomycosis because of the chronic/recurrent clinical course and radio-pathological findings such as a granuloma lesion. Although a biochemical analysis revealed Actinomyces sp., 16S rRNA gene sequencing and a phylogenetic tree analysis of the isolated strain confirmed the presence of E. brachy...

OBJECTIVE: To compare the characteristics and outcomes of patients who underwent surgical treatment for stage 2 medication-related osteonecrosis of the jaw (MRONJ) versus osteomyelitis. METHODS: This retrospective study compared the following variables in 73 patients with stage 2 MRONJ versus 89 patients with osteomyelitis: impaired wound healing after surgery, sex, age, the presence of actinomycosis, location of the jaw lesion, and involvement of the inferior alveolar nerve (IAN)...

Pulmonary actinomycosis is a rare bacterial lung infection which is caused mainly by Actinomyces israelii. This non contagious infection can destroy parts of the lungs. There are variable presentations of pulmonary actinomycosis with similarity in manifestations to other infectious diseases of the lungs. Pulmonary actinomycosis is diagnosed by fine needle aspiration, bronchoscopy and finding of typical sulfur granules. We present a case of pulmonary actinomycosis in a middle aged (AIDS/HCV) man with massive hemoptysis and progressive dyspnoea...
